Detailed description of the invention
Below by embodiment and combine accompanying drawing, the invention will be further described:
Shown in Fig. 1 Fig. 4, a kind of head pillow frame fold mechanism, mainly by head rest pole 1, " n "
The headrest support 2 of shape, folding rotary shaft 3, fixed plate 4, folding button 5, headrest base skeleton 6, unblock
Frame 7, locking plate 8, button return spring 9, locking plate return spring 10, unblock rotating shaft 11, set bar
12, fold spring 13, solve lock support back-moving spring 14, lining 15, gripper shoe 16, trip bolt 17 etc.
Composition.Headrest base skeleton 6 uses EPP rigid foam to make, and covers on headrest support 2, and by two
Trip bolt 17 is fixed.Headrest support 2 uses steel plate punched to form, overall in " n " shape, headrest
The two ends of frame 2 head rest pole 1 with respective side respectively is hinged on folding rotary shaft 3.
Fixed plate 4 is welded on the flattening portion, upper end of a wherein head rest pole 1, and is pacified by this fixed plate 4
It is contained on folding rotary shaft 3.In addition to the upper end of the head rest pole 1 welded with fixed plate 4 uses flaser texture,
The upper end of another root head rest pole 1 is preferably also adopted by flaser texture, is welded with gripper shoe 16 in this flattening portion,
And be arranged on folding rotary shaft 3 by gripper shoe 16.Fold spring 13 to be sleeved on folding rotary shaft 3, solve
The two ends of lock rotating shaft 11 are separately mounted on the two side of headrest support 2, and are positioned at the upper of folding rotary shaft 3
Side.
Button return spring 9 is sleeved on the bar portion folding button 5, and the termination folding button 5 is positioned at headrest
Outside base skeleton 6, button return spring 9 is for folding the self-return of button 5.Fold the bar of button 5
Portion pass perpendicularly through headrest the sidewall of base skeleton 6, headrest support 2 sidewall after be against solve lock support 7 upper
On the wall of side.Preferably, fold and be provided with the most uniform anti-rotation tenon on the bar portion sidewall of button 5
5a, prevents folding button 5 and rotates.
